9 Claims. (Cl. 223-73) This invention relates to trouser topping apparatus and more particularly to the buck and bag assembly employed therewith.

Many improvements have been devised in conventional trouser topping apparatus for the supplying of the processing fluids, the clamping of pleated trousers, and the relating of accessory apparatus to the topping machine whereby the operator may increase his output of work without undue fatigue. However, in the last analysis, the operator must still position the trousers in proper position on the buck, employ his skilled judgment as to the processing required, and finally remove the processed garment from that buck. In order to obtain an optimum quantity of work and with an optimum quality of work, the operator is dependent upon the construction and capabilities of the buck and bag provided for the machine.

For example, the buck and bag should be capable of use with a wide variety of sizes of garments, and types of garment fabrics; should be padded sufficiently to permit clamping of pleated trousers against the buck but without seam imprinting; should be capable of being dried quickly; and should be arranged for detachable mounting upon the remainder of the topping apparatus. Thus it is a purpose of the .present invention, by means of an improved buck and bag assembly having the above capabilities, to overcome certain disadvantages and handicaps formerly imposed upon the operators of trouser topping machines.

An object of the invention is to provide a buck and bag assembly for trouser topping apparatus by means of which the wrinkles in the crotch of the trousers are easily and rapidly removed.

Another object is to provide a buck and bag assembly by means of which the seat of trousers'is shaped in proper form.

Another object is to provide a padded buck and bag assembly capable of rapidly diffusing the flow of processing fluids therethrough.

A further object is to provide an improved contoured buck shaped and padded to fit the tailored cut of trousers.

A still further object is to provide an improved bag and means for mounting the same upon a buck, in a manner permitting ready removal of the same without dismantling the machine parts. I

Other objects and advantages will become more apparent as the description proceeds and when considered in conjunction with the accompanying drawings in which;

FIG. 1 is a perspective view, with parts broken away of a trouser topping machine equipped with the buck and bag assembly of the present invention and showing FIG. 4 is a detail sectional view taken to a larger scale on line 44 of FIG. and showing a drawstring mounting arrangement. r

FIG. 6 is a perspective view of a buck plate detached from the machine and showing the steam connections therefor.

FIG. 7 is an interior view of the buck plate facing toward the front of the machine and showing the mounting of the envelope and pad.

FIG. 8 is a front elevation view of the padded buck and attached bag with portions broken away.

FIG. 9 is a side elevation view of the bag when fully distended and with the apex of the ridge of the crotch portion being indicated by an inclined dotted line;

FIG. 10 is a sectional view of the bag taken on line 1010 of FIG. 9, and FIG. 11 is a rear elevation view of i the bag with interior elements shown in dotted lines.

In accordance with the invention, a trouser topping apparatus having supplies of steam and hot air under control of the machine operator is provided with a perforated concavo-convex buck which includes an abdominal con figuration having truncated leg surfaces separated by a crotch portion. This buck, which normally is heated, is furnished with a perforated resilient pad encased in an envelope of fluid-pervious, heat-resistant fabric material and to that envelope the front of a distendable, fluidpervious bag is attached. The bag includes truncated leg portions, a seat portion, a waist portion, a mouth portion for receiving processing fluids, and a ridge portion extending centrally through the seat portion of the bag from the crotch area to the center rear area of the waist portion and adapted to shape the dividing seam region of a pair of trousers positioned upon the buck and bag, said ridge portion having a vent therein for directing fluid to the corresponding region of trousers disposed over the bag, whereby crotch wrinkles are easily removed during the finishing of such trousers. Means also is provided for urging the bag into interior contact with the waist band of the trousers prior to supply of fluid to the bag and for collapsing the bag, after processing is finished, in order to permit rapid removal of the trousers from the buck and bag assembly.

Referring now to FIGS. 1 and 2, any trouser topping apparatus of suitable nature, but preferably of the type described in my copending applications, Serial No. 180,- 069, filed March 12, 1962 and Serial No. 184,627 filed March 12, 1962 and assigned to the same assignee as the present invention, may be employed. Such an apparatus comprises a base 10 adapted to rest on a floor and with parallel side walls 11 and 12. A generally vertical back wall 13 and a sloping front wall 14 complete the vertical housing. Communicating with the interior of that vertical housing is a generally horizontally extending air duct portion comprising a single sheet having a right hand side wall 15, a left hand side wall 16, and a curved front wall 17; the terms right'hand and left hand as used herein referring for convenience to the parts as viewed from the operators positions. These side walls converge toward each other, as best seen in FIG. 3, and cooperate with a fiat floor plate :18 and a fiat cover plate 19 (FIG. 5) to define the air duct portion of the housing. The floor plate terminates along a forwardly projecting arcuate edge 20 (FIG. 5) spaced from the front wall 17 of the air duct to provide an opening 21 through which air may pass from that duct into the bag later to be described.

As further shown in FIGS. 3 and 4, the arcuate edge of the floor plate is recessed at 22 to receive a bag-mounting drawstring adapted to be anchored upon pins 23 and 24 rigidly fixed to the underside of the floor plate and i the manner later to appear.

Passing now to FIG. 6, the invention includes a specially 3,1eaeee transfer characteristics and preferably of a metal which is not affected by cleaning materials. This plate includes an upwardly extending band portion 30' adapted to be rigidly mounted against the inner surface of the curved front wall of the air duct and merging into right hand and left hand convex shaped abdominal portions 31 and 32 respectively and which in turn extend into truncated leg surfaces 33 and 34 separated by a crotch port-ion 35. The plate, moreover, is perforated by means of a plurality of generally equally distributed small holes 36 extending therethrough. For the purpose of supplying both conditioning and buck-heating steam to the bag and buck assembly a system such as shown diagrammatically in FIG. 2 may be used, and includes a steam inlet pipe 4i) leading to the central region of a conventional separator 41 mounted Within the housing. From the lower end of this separator wet steam and condensate passes through a conduit 42 to the upper end of an inclined heater 43 across which all air moving into the air duct passes. Condensate from the heater passes to a collector 44 located at the rear of the housing. From the upper end of the separator one conduit 45 leads dry steam to a solenoid valve 46 from which a conduit 47, located within the air duct portion of the housing directs such steam to a header 48 affixed in heat exchange relation to the buck plate as seen in FIG. 6.

This header extends into a pair of perforated conduits 49 and 50 having spaced holes therein serving to direct dry steam into the bag for the purpose of conditioning trousers emplaced on the buck and bag. As best shown in FIG. 7, the jetting of steam from these conduits is substantially obstructed by a plurality of asbestos boots 51, 52 and 53 mounted upon brackets placed on the concave inner surface of the buck plate, and which boots serve to diffuse the condition steam and to permit it to move into the interior of the bag and also to bleed through the holes 36 in the buck plate. From the upper end of a separator 4-1 another conduit 54 leads dry steam for buck heating purposes to a conduit 55 which has loop portions 56, 57 and 58 affixed in heat exchange relation to the buck plate and connecting as acontinuous conduit with return conduit 59. This return conduit leads to collector 44 by way of an interposed water leg 60.

Mounted adjacent the base of the housing is a blower 65 having end intakes 66 and 67 and driven by an electric motor 6 8. Air moved upwardly in the housing by this blower passes above the inwardly offset wall69 and across the heater 43 and thence into the air duct portion of the housing and downwardly through the opening 21 into the open mouth of the bag. In this passage, the heated air also passes through the aperture of a partition 70 (FIG. 1) controlled by the setting of a damper '71. The described supply means for air and conditioning steam are actuated as desired by the operator and may include control apparatus of the type and at the locations more specifically set forth in said copending application Serial No. 184,627. In general, such controls include switches, not shown, housed Within a sealed receptacle 72 (FIG. 7) and actuated by buttons 73, 74 and 75, located on the exterior of the curved front wall 17 of the air duct housing (FIG. 1),. and with cables 76 leading. from such switches'into an electrical control box 77 (FIG. 2) located at the rear top portion of the housings.

As further disclosed in said application Serial No. 184,- 627 and as shown in FIGS. 1 and thereof, I provide an improved waist-expander mechanism for use with the bag and buck assembly ofthe present invention. This preferably comprises a bracket 86 mounted upon the interior rear wall 13 of the vertical housing'and supporting a metallic retracting means such as the Negator type of spring assembly, having a drum 81 of convolutely wound thin strip material 82 adapted to provide a constant and uniform retracting force throughout its Working range of deflection, which for purpose of the present invention, may be aboutv one foot. The strip 82 extends througha slot in the upper end of wall 14, and as best seen in FIG. 5 has its forward end attached to a slide 83 movable longitudinally of a slotted guide 84- afiixed to the underside of the floor plate 18 of the air duct portion of the housing. By means of a latch, not shown, operated by manipulation of the knob 85 projecting from the front Wall 17, the slide is released from latched position, so that it may be drawn to the rear by the drum $1.

Considering now FIGS. 5, 7 and 8, the entire convex surface of the heated buck plate is padded by means of a pad 99, which pad preferably is formed of a heat-resisting, synthetic air-foam rubber material having a plurality of perforations distributed equally over its entire surface. An envelope formed of heat-resisting, fluid-pervious material encloses the pad, and the inner layer 91 of the envelope, interposed between the pad 0, and the surface of the buck plate, consists preferably of a double layer of material; the layer engaging the surface of the pad 9% being a relatively-heavy, coarsely-woven asbestos cloth, while the layer engaging the surface of the buck is a relatively-light, finely-Woven asbestos cloth.

The outer layer 92 of the envelope, which is engaged by the trousers placed upon the buck, consists preferably of a single layer of relatively-light, finely-woven cloth consisting of both Nylon and asbestos yarns, generally known in the trade as Nylon-asbestos press cloth.

The outer layer 92 of the envelope is provided with a hem 93 across the top portion thereof, through which a bag supporting drawstring 94 extends (FIG. 5

The inner layer of the envelope is provided with a tongue or flap, across the top portion thereof, which tongue is folded over the top edge :of the pad and downwardly over the upper front surface of the pad engaged by the outer layer '92. This serves to assure that the entire surface of the pad engaging the heated buck is covered by the heat resisting inner layer of the envelope, and, if desired, the tongue may be attached at points along the fold line thereof to the upper end of the outer layer of the envelope.

At the sides and bottom of the envelope, where the inner layer 91 and outer layer 92' are joined, hems 95 and 96 are provided through which a separate, bag-supporting drawstring 97 extendsrrthe drawstring 97 being trained over pins 98 and 99 and fastened tosthe centrally located bracket 1%, (FIGS. 4 and 7), which bracket is mounted upon the forward end of the floor plate 13.

Tightening of the drawstring -97 serves to hold t e envelope and its pad firmly in place upon the convex surface of the perforated buck plate, and since the pad is also perforated, and both the inner and outer layers 91-92 of the envelope are fluid-per-vious, 'air and conditioning steam may uniformly pass into contact with the trousers supported upon the buck.

To assist in holding the drawstring 97 taut, and to avoid any tendency of the pad to shift after'repeated usage of the appanatus, a pair of tension springs 101, 162 are provided, and these are clamped to the juxtaposed hems 95j96 (FIG. 7), to provide lateral tension between the hems 95-96 across the open concavepo-rtion of the buck, thus holding the pad taut over the conver surface of the buck.

An arcuate clamping member 1% (FIG. 5), fastened to the front wall 17 of the machine by screws 1%, further assists in holding the described pad and envelope assembly tautly in place.

Referring now to FIGS. 8 and 9, a distenda-ble bag formed of a suitable fabric such as Nylon having a porosity adapted to provide proper steaming and air drying of trousers placed upon the buck, is employed in combination withthe above described padded buck. The aforesaid bag is preferably cut to a pattern providing maximum fidelity in finishing and shaping the top portion of trousers, and the'front portion of this bag is stitched to the outer surface of {the outer layer $2 of the envelope along the stitch line 1% inboardof the periphery of the bifurcated outline of the buck plate. *Right and left wall portions 106-5107 extend rearwardly of the stitch line 105, and merge with each other at their rear extremities at a location corresponding substantially with the upper rear waist-band portion of the trousers. A sliding fastener diagrammatically indicated at 108, is located in the right panel 106, to provide easy access to the interior of the bag and padded buck.

The side walls 106, 107 merge also along their lower and intermediate extremities into a seat portion 109, and an arcuate plate 110, preferably constructed of several overlying sheets of flexible material, is mounted inside the bag in contact with the upper rear waist portion of the bag. In the preferred embodiment of the invention, the arcuate plate 110 is constructed of three pieces of linen reinforced phenolic sheets each about .032" thick, and these overlying sheets provide sufficient flexibility so that they will flex to conform with the shape of the extended waistband of the trousers.

Joined to the side wall portion 106-107 and to the waist portion, is a top cover portion 111 preferably of two thicknesses of Nylon cloth so as to restrict the flow of steam and air through this top cover, since no portion of the trousers is to be in overlying contact with this portion 'of the bag, and accordingly, air under pressure might otherwise escape through top cover i111, if it were not made less pervious than the described seat and side portions.

The top portion 111 extends forwardly to the edge of floor plate 18 and has a hem at its forwardmost edge into which the drawstring 94 extends.- Accordingly, the same drawstring 94 which passes through the hem 93 of the envelope may be trained about the pins 23 and 24 and rest in recess 22 ('FIG. 4) thus to hold the forward portions of the bag in place during the expansion and contraction of that bag, it being understood that the space between the hem edge of the bag and the buck plate serves as an open mouth for the cover portion of the bag, this month coinciding with the aforementioned opening 21 in the air duct.

Extending between the crotch of the buck plate and through the seat portion of the bag to the center rear area of the waist portion thereof, the bag material adopts an upwardly directed, ridge-like configuration the apex of which is disposed closely adjacent the leg and buttock separating seam of the trousers, herein called the dividing seam. This ridge is indicated generally by the dotted line 112 in FIG. 9 and the apex of this ridge from region 113 to region 114 has its side walls 115 and 116 separated from each other to the end that steam and air may pass directly into contact with the dividing seam of the trousers.- As shown in FIG. 11, an elongated vent thus is formed in the ridge portion of the bag and through which processing fluid may contact directly the dividing seam of the trousers emplaced on the bag. Wrinkles in those trousers adjacent that seam are promptly and elfectively removed during the processing by reason of this arrangement.

The bag, preferably, but not necessarily, is closed at its lower regions 117 and 118 corresponding to the truncated leg portions of the trousers in order to diminish the escape of steam and air from the interior of the bag. In its top cover portion 111 adjacent the plate 110 a small hole is provided for receiving a rod 120 the upper end of which is ailixed to slide 83 (FIG. 5). This rod extends through bracket 121 pivotally mounted thereon and held in place by a win-g nut or the like 122.

The bracket in turn is affixed to and supports the plate 110 and is normally urged to bag expanding position by the slide which is attached to the retracting spring element 82. When it is desired to remove the bag, merely removing the wing nut will permit the bracket, attached plate 7 when considered in connection with a normal cycle of trouser topping. Assuming that the pad and bag are dry and that the buck plate is heated normally by the steam passing through convolutions 56, 57 and 5 8, the operator raises the pleat-setters 125 and 126 (FIG. 1), places his hand against the plate at the rear waistband region of the bag, and pulls it forward against the action of spring 32 until the slide is latched. The trousers are then lifted into place with the back center of their waistband high upon the plate 110 and are then pulled forward, and the hook, button or snap front of the waistband thereof is fastened, but with the fly closure remaining open. While holding forward tension on the trousers the knob 75 is pushed to unlat-ch the slide and as the plate 110 retracts, the trousers are held against the face of the padded buck. The thus held trousers then are adjusted and centered, as necessary, upon the buck, after which the controls for supplying steam and heated air in the desired sequence and amounts are actuated.

As conditioning steam enters the bag, it is diffused by the boots 52, 53 and 51 and fills the entire spaced within the bag but, due to the cover portion 111, is largely confined within the bag for passage into contact with the interior trouser surfaces and through the padded buck. It will, however, be seen that since a section of the ridge portion of the bag is vented as at 112A, some steam passes directly from the bag into contact with the dividing seam of the trousers.

Following the steam conditioning, which may be either a preconditioning stage as when pleats need to be softened, or an automatic steaming either with simultaneous or subsequent supply of heated air, the bag is then filled with air under pressure from blower 65 as modified, if desired, by an adjusted setting of the damper 71. As this air enters the bag through its open mouth communicating with opening 21, the following significant features of the invention are accomplished. The previously moistened trousers at this time are being held in a conformation which closely corresponds to the tailored cut of the same; the abdominal portion being in contact with the convex surface of the padded buck and the waist band of the trousers being in contact with the upper sides and upper seat portions of the bag. As heated air under pressure then enters the bag for a period of time, for example, of about 20 to 25 seconds, the bag distends at its sides and seat and in the truncated leg portions thereof, thus bringing the ridge portion of the bag into close proximity to the dividing seam of the trousers and shaping these areas of the trousers without disturbing the waistband area or the abdominal area which already have their proper shape. If, at the same time the pleats of trousers are being shaped on the machine, the bag distention will in no way interfere with that operation.

The use of the Nylon bag material, which may be specially Woven to give a predetermined porosity, as well as being cut to a pattern which approximates the pattern of cut of tailored trousers, further contributes to the proper shaping of the seat region of the trousers as the bag fills out under pressure of the heated air.

As soon as the trousers are topped, the supply of hot air is interrupted, the plate 110 is pulled forward to latch the slide 83, and with the bag thus collapsed, the topped trousers are easily slid downwardly off the buck and deposited on a legging out bench for final creasing. Accordingly, a high quality of work is obtained while at the same time permitting the accomplishing of a large quantity of work without undue operator fatigue.

The mounting of the bag and of the perforated pad is such that a substitute bag and pad may be easily substituted whenever necessary. Moreover, the perforated pad and the porous envelope therefor are well adapted for rapid drying in case they should become wet 'due to malfunctioning of the steam system or to improper overation by the machine operator.

Various changes may be made in the details of construction Without departing from the spirit and scope of the invention as defined by the appended claims.
